THERMAL GAsIrYING Moron CONSTRUCTION.

Application ined Janna-ry 3c, 1922. serial No. 532,923.

This invention relates to a newmotor construction, more particularly to a construction of internal combustion engine embodying means to obtain a. better and more adequate cooling of the motor, an increased efficiency of the fuel charge and better lubrication than possible in ordinary motor construction. y f

To that end the present invention is based v-on certain fundamental factors' that enter into'the successful operation of the `invention. One of the primary object-s of the invention is to provide a construction-which may be in the form of la crown for the motor bloc or othrwisewhi'ch eiectuallycools the engine, reduces the` temperature in the crank Y relies.

mentals, the following observations are vto case and at the saine time supplies h eat and moisture for the purposey of obtaining the increased efficiency of the fuelvcharge..

The above mentioned general objects ofk the invention involve certain "fundamentals upon which the invention to a large extent In explanation `of those, fundabe noted, to wit:*The action o f heat alone on fuel to be .used for ,combustion purposes is not adequate in the process of breaking up the molecular construction of the fuel.` Therefore, Vthe present invention involves;

f the incorporationof moisture with rthe fuel charge whereby the skin of the molecules will be caused to swellrendering the same susceptible to air friction and 4to breaking upymaking a true gas for the combustion. In that vconnection it is well knownthat the ordinarymixing devices and carburetorsfin;

1 particles, asa mist, as distinguishedfrom a .liquid completelybroken up into a true gas as is 'provided for by the present inventionr.

fying thefuel and incorporating with it the vIn ,its application'to air cooled motors the y invention possesses special utility inasmuch Y as itjpresents-a construction `Vwhich lpermits the use of theV fuel asa .cooling medium for A j necessarily .susceptible of embodiment in vaiprovenient rin .motor construction involving the car-ryingout of a `process of making a true gas-.and lowering the heat in the motor vcylinder l'where the "friction hea-tk is usually .excessively developed, thus preventing the oil Iin the crank case from becoming unduly thinned from unexploded'gas and by the n excessive frictional heat. Carbon deposits will therefore be eliminated and the-socalled pre-ignition will 4be preventedfl Another important obj ect of the inventioin is to introducefmea-ns of asuitable' charac? ter, such for eXampleas a fan, in the crank case of the motor so that such means o'rfan will assist circulating the-vapors, andthe air takenv in through the breather` pipe or fromA another'source against the metal partsjand wallsl serving to reducel the ,temperature y and therefore-cool the oil, thus con's'erving'and preserving tlhe lubricant qualities of the-oil to the maximum degree. At thesame time v the means-or fanreferred to maybe of such :a nature yas toy operate under the iniiuence of the suctionl of the'motor and thereby assist in directing the crank case gases tothe fuel supply. v`Furthermore, themeans or fan re-l ferred to ,operates to ,circulatethecrank case gases in such a manner as to not` interfereor mix with the solid or' body part-sof 8 the lubricant whichl are thrown up4 into the cylindersffor lubrication, thus permitting Y.

-one of itsspeciic objects the embodiment ofthe invention in what may be termed as a@ thermalgasifying crown for the'motor, that is to say, .also-called removable head having the capacityfforvusing the fuelas a cooling medium and also involving means for gasi-y moisture and thegases from thecrankcasc, producing the true highly explosivegas. p j In carryiigout theinvention the same is rious formsj ofy construction without departing fromthe spirit or principle thereof,'but

' y'In the construction shown the novel crown .or head@ takes the Place of the sore'llefl motor head tvhshmay 0r may 119th@ removgfible, but ha@ illustrated form ,ofthe pres A"ent invention the `said `crown or yhead is shmvn as beine' .remet/ably ,held in Place ylav bilts lectedat suitable .and 'cervr'ent points. A distinctivefeatureof this crown or'lhead construction isMthe' sameheing provided' with an' interior' gasifying (':hamloer 'has'rrojctng therein ,rlilfaltr .df .heie i .n'imbersa rreferablyfhollow) arranged in .rlsgenatedlbythe numeral '1. 'This chamber the fuel vapor` passes on `its wayto the intake valves'. Also as shown in Figure 2 the crown C'is provided with openings for re- -ceivingthe spark plugs Spin the vusual rmanner.

, yIt will now befseen that the gasifying chamber l in the crownA receives the atomized "fuel from'the carburetor through the pipe 5 and also receives the gases from the `crank 'c'a'se through vthe pipeS which'is connected with the offset or recess R in the crank-case which'fhouses vthe circulating fan F, which isexpo'sedto the interior of tlie'crank case but presentsno projection beyond the -line ot. "the inside vwalls of the case. The, 'said fan F operates'v to' circulate the vapors yin the crank caseand the air takenlin through the breather pipey or 'other Asourcethereby serving toi'reduce' 'the `temperature"within the crank Case'and coolin'glthe lubricating oil.

Bylpreservl'n'g a' morelnormal temperature or'the oi-l, 'the lubricating qualities thereof are conserved.l Tha-t is to'say, by preserving a safe temperature within'th'e crank Vcase the" lubricating oil is not distilled -i'n-toits liner 'constituents which possess little or no lubricating qualities while at the same time the circulation of atmospheric 'airdueto the siicremove any of the `fuel gas which escapes the pistons on'v the 'compression'stroke and :fur-

ther prevents the disintegration of the oil to prevent oilbe'ing thrown up fintot-he pipe "8 by the vsplash from the crank lshaft which is very' considerable at'fhigh speeds.

" Also inea'nfsvs 'provided oradniittingat- '-inospheric air into the said gastying chambei"fancl"while that Amay bedone in rvarious waysfagconvenient and practicalmea'ns of accomplishing "that resultfis suggested 'in'.the drawings', namely to provide vthe fuellpipe 5 rwith'lan air intake valve 9. Therefore; the

pointed "init",A 'this y desirable esiilt is Ifaciliele-prepay vvC'ori* veateri ra atteggia-@ous stare. fTliats to say', the liquid "eeoledehambe' 1 tion in 'the'pipe `8 and fan F serves to 'also'v requisite moisture in ythe charge to insure its eficiency and as a rmatter, of fact serves tocondense the moisture taken in from the outside air and also from the gas in the crank case thereby to` insure an adequate degree of moisture in the heater mixture. l

While the present device is particularly adapted to thoroughly gasify the fuel charge to be used in the engine, and at the same time pre-heating the same without over-heating, nevertheless the construction may also be used for pre-heating and gasifying relatively heavy fuel oils such as kerosene and the like which are especially adapted for use in con-4 nection with motors for tractors and other heavy duty work.' That is to say, instead of the intermediate chamber 1 of Figure 3 being used to conduct the vaporsy to the inlet valves of the motor7 it preferably communi- Cates with a source of fuel supply S `by lmeans of the pipe l0. After the fuel oil has been thus preheated in the chamber l it may be conveyed by the pipe l1 to the carbureting device 12 to be atomized and supplied to the intake manifold of the motor in the usual manner. Thus, we have a construction wherein the fuel, such as kerosene, is employed as both the cooling medium in vthe jacket of the device and also as the fuel for the motor and this feature is particularly valuable in connection with air cooled motors.l f

Itis a well known fact that tractor motors by reason vof their. heavier construction develop a very high degree of heat and while a water cooling system isutilized to reduce this heat, nevertheless an additional cooling effect may also be obtainedby passing a normally cool fuel oil throughthe pre-heating chamber l. As previously explained ,the

less than the firing heat of the fuel `and it is therefore, relatively speaking',cool. Nevertheless, the fuel in passing throughv the chamber l absorbs some heat which has the advantage of raising its temperature while y at the same time absorbing heat from the circulating system, thereby obtaining the desirable veffect of perliminarily pre-heating the fuel and cooling the` motor simultaneously;

vithout further descriptionit is thoughty that the features and 'advantages of lthe present improvement will bev readilyv apparent, and it will of course be understood that changes in the form, proportion and minor r details of construction may be resorted to Without departing from the spirit ofthe iny vention or scopevof the appended claim.`
